How to create vector index property?

[eyueldk]

How can I create a vector index property in neomodel?

I tried the following (as mentioned here), but the index is not created in neo4j.

class Embedded(StructuredNode):
    embeddings = ArrayProperty(
        FloatProperty(),
        vector_index=VectorIndex(384, "cosine")
    )

Hi @eyueldk , did you neomodel_install_labels after modifying your data model?

[eyueldk]

No I didn't. Thank you for making me aware of that. Much appreciated.

No worries, glad it was something as straightforward as that, all the best :)
